The container 61 can be easily accommodated and installed in the fumigation pot 6 with the part 61 opened, and the container 7 can be easily and easily taken out and inserted into and removed from the fire extinguishing container 9 upon completion of the fumigation. In the suspended state of the above, by unlocking the fixing device 77 and opening the bottom cover 75, the carbonized bamboo W can be quickly taken out by discharging it downward while preventing the shape of the charcoal from being deformed. You can do it.

In this embodiment, a catalyst body 71a composed of a copper rod or a rod formed by plating a metal rod with copper or the like is arranged and fixed in the middle of the plurality of vertical frames 71 at predetermined intervals. A large amount of bamboo W accommodated in the container 7 is formed by the catalytic action of promoting the extraction of the bamboo vinegar component from the bamboo W during heating while promoting the temperature rise in the fumigation chamber 66 due to the presence of the catalyst body 71a. Even in a relatively low temperature range, the extraction of bamboo vinegar is performed substantially uniformly and quickly, and the catalyst 71
The a itself is used as the vertical frame 71 member so that leakage of the bamboo W inside can be prevented well with a low-cost configuration. The means for installing the catalyst body 71a in the fumigation chamber 66 is not limited to the above-described one, and the catalyst body may be formed into a catalyst pair with a ring frame 70, or may be formed in a plate shape or a block shape along the shuttle 60. It may be installed by sticking or attaching and fixing, or a catalyst body formed in a ring shape as shown by a dotted line in FIG.

Next, the fire extinguishing container 9 will be described.
The fire extinguishing container 9 has a container main body 90 for accommodating the container 7 at a small interval so as to be able to be inserted into and removed from an upper opening, and a lid for opening and closing the opening around a support shaft 91a so as to be airtightly closed. The fire extinguishing vessel 9 is configured so as to be installed near the heating furnace 2. Thereby, the container 7 containing the bamboo W in a red-hot carbonized state immediately after being taken out from the fumigation pot 6 can be quickly and quickly accommodated in the container main body 90 without burning by contact with air. After the storage, the lid 91 is airtightly closed to prevent oxidation, and the carbonized fumigated bamboo W in the container 7 can be uniformly and well carbonized to provide high quality activated carbon or the like. What you can get.

The fire extinguishing container 9 has a cooling chamber 93 with a water supply / drain pipe 93a connected to a water source capable of circulating cooling water in the container main body 90, as shown in the illustrated example. Connecting pipe 9 of deaerator (not shown) for extracting air
In this case, the inside of the container 7 can be quickly cooled by the cooling water, and the oxidation of the bamboo charcoal can be prevented by deaeration, so that good and hard bamboo charcoal can be efficiently and easily produced. There are advantages such as being able to be provided.

The fire extinguishing container 9 is provided with a water supply port 97 communicating with a water source so that an appropriate amount of water can be freely stored in the container main body 90, and a drain 99 capable of appropriately discharging the internal water is provided. By doing so, the entire container 7 containing the fumigated material W may be immersed in water. Thereby, after the fumigation of the material W is completed in the fumigation pot 6 and the bamboo vinegar component is extracted, the container 7 taken out of the fumigation pot 6 is replaced with a fire extinguishing container 9 storing water.
When it is inserted into the water and submerged, the material W is cooled at once from the red heat state, so that the material W rapidly decreases in temperature and becomes porous while generating fine internal cracks, and the material W is uniformly impregnated with water. Then, the material W can be self-promoted by the activity of the steam generated at this time.

Accordingly, the bamboo charcoal which has been cracked while being impregnated with water and which has become softened has advantages in post-processing work such as extremely simple and efficient pulverization in small and uniform manners, as well as conductivity. Thus, the activated carbon can be improved as a highly conductive activated carbon, and can be suitably used as a soil improvement material or a compost production promotion material, which can suitably grow microorganisms such as bacteria in the soil. Also, it can be effectively used as a purification material such as air and water. When the material W is cooled as described above, a small mesh basket (not shown) may be housed in the fire extinguishing container 9 in advance. In this case, the container 7 is placed in the basket. After the cooling, the basket is put in the fire extinguishing container 9 together with the container 7.
, The finely pulverized coal particles can be easily collected.

The extraction apparatus 1 configured as described above
By the following method, a good amount of bamboo W is cut from the large amount of bamboo W cut into an appropriate length and accommodated, while suppressing leakage of smoke and the like, while saving energy as much as possible and saving energy. Vinegar can be efficiently and easily extracted, and bamboo charcoal after bamboo vinegar extraction can be efficiently and easily obtained while preventing oxidation, and effective utilization of charcoal can be achieved.

That is, the extraction device 1 according to this embodiment
As shown in FIGS. 1 and 4, 500 kg of bamboo W is placed in the fumigation kettle 6.
After the container 7 accommodating the bamboo W is placed in the fumigation kettle 6 and the lid 61 is closed and the heat generator 2a is operated, the fumigation kettle 6 and the heating chamber 23 are heated. And the temperature in the fumigation kettle 6 is extracted to approximately 400
With a rise in temperature to about 600 ° C to 600 ° C, a large amount of bamboo W
The bamboo vinegar component and the like can be taken out together with the moisture in the bamboo W while the red carbonization of the bamboo is homogeneously promoted in the air-blocked state. The extraction operation can be completed with the processing time.

The fumigation body taken out of the fumigation kettle 6 is subjected to a filter 3 to remove tar components in advance,
By storing in the storage tank 5 while being liquefied by the condenser 4, bamboo vinegar with less impurities can be obtained efficiently and accurately, and the container 7 can be quickly taken out of the heating furnace 2. Therefore, unlike the conventional means of extracting bamboo vinegar and wood vinegar, the material is not burned or smoke is exposed to the air, so that almost the entire amount of bamboo vinegar can be accurately extracted from the material. In addition to this, there is an advantage that high-quality bamboo vinegar can be efficiently obtained in a short time.

At this time, according to the present invention, since heating is started in the fumigation kettle 6 in a state where a predetermined amount of water is previously stored in the bottom thereof, the fumigation kettle 6 is close to the heat generator 2a in the initial stage of heating. Rapid heating and temperature rise at the bottom of the pot
The damage to the kettle can be prevented well, and the temperature of the whole inside the fumigation kettle 6 can be quickly and uniformly increased by boiling the water at the bottom to form steam. Accordingly, the heating furnace 2 can save energy and perform efficient fumigation by that much, and at the same time as the temperature in the fumigation pot 6 rises, the steam almost uniformly contacts the bamboo W in the container 7. ,
Since the steaming action on the heated bamboo W is favorably performed, there is an advantage that the extraction of the bamboo vinegar component in the bamboo W can be promoted as much as possible.

[0037] According to this, even bamboo W, which has been dried, can be satisfactorily wetted in a heated state, so that there is an advantage that the bamboo vinegar component can be easily extracted. Further, in the case of the fumigation kettle 6 in which the nozzle 68 for water supply is installed above the kettle part 60, a desired amount of water can be sprinkled on the bamboo W in the container 7 from above in a timely and favorable manner, There is a feature that bamboo vinegar extraction can be easily controlled.

Further, for example, when it is desired to carbonize construction waste materials such as wood, bamboo material, synthetic material, and paper material which have been subjected to a preservative or a chemical treatment, the construction waste materials are temporarily removed. It is easy to fumigation after it is in a wet state, and it is good to take out harmful substances contained or attached to waste material (material W) together with water vapor that generates a large amount in the early stage of fumigation, and good with vinegar etc. contained in waste material Moreover, since it is possible to accurately extract and remove the waste coal, there is an advantage that it is possible to easily obtain waste coal in which the content of harmful substances is suppressed. Further, there are advantages that the above-described construction waste material treatment can be easily performed, and that effective utilization of carbonized resources can be easily achieved. In addition, the present invention is not limited to the method of extracting bamboo vinegar and the like, and may be used by specializing as a method of carbonizing construction waste material as described above. The liquid may be used or disposed of with further processing.

In the above fumigation process, the fumigation pot 6 is heated to such an extent that the bamboo W does not turn red, and then the fumigation pot 6 is heated.
After temporarily stopping or lowering the temperature inside and then controlling the heat generator 2a or the like to heat to the extraction temperature, the bamboo W is temporarily heated and then temporarily stopped. Since the entire bamboo W in the container 7 is evenly heated to approximately the same temperature, and enters an extraction standby state in which only the initial release of water vapor is suppressed, the bamboo W is reheated and the temperature is raised to an appropriate extraction temperature. Advantageously, it is possible to uniformly and satisfactorily extract bamboo vinegar from the entire bamboo W packed in a large amount in the large container 7.

The container 7 containing the bamboo W is installed in the fumigation pot 6 so as to be insertable and removable, and the container 7 taken out after the completion of the fumigation is accommodated in the fire extinguishing container 9 placed close to the heating furnace 2. As a result, the interior of the fumigation kettle 6 can be quickly emptied, and another container 7 containing the bamboo W can be quickly installed in the fumigation kettle 6 again.
The new bamboo W can be continuously fumigated while preventing the temperature drop and utilizing the residual heat, so that the fumigation work can be performed efficiently while saving energy and the vinegar solution is continuously and efficiently extracted. There are features such as being able to do.

On the other hand, the container 7 containing the bamboo W in a red-hot carbonized state immediately after being taken out of the fumigation kettle 6 can be promptly accommodated in the container body 90 located near the heating furnace 2 and accommodated. After that, by closing the lid portion 91 airtightly, oxidation is accurately prevented while suppressing large burning of the bamboo charcoal, so that the carbonization of the bamboo W after fumigation can be performed uniformly and well, and There is an advantage such that the use of the material can be widely promoted.

[0042]

A material for extraction such as bamboo vinegar is removably accommodated in a fumigation kettle installed in a heating furnace, and a fumigant generated by heating the material in a sealed state is taken out and sent to a condenser. By extracting the vinegar liquid by liquefying the smoked body,
It is possible to perform good fumigation while saving energy while preventing leakage of smoke and the like in a state where the contact between the material and the outside air is cut off, and it is possible to efficiently and easily extract a high-quality vinegar solution.

Further, by performing the fumigation operation in a state in which water is supplied into the fumigation kettle, the temperature in the fumigation kettle can be quickly raised by generation of steam while preventing damage to the kettle and the like. Therefore, efficient fumigation can be performed while saving energy.

Further, since the material to be taken out together with the container after completion of the red-hot carbonization of the material is submerged in the fire extinguishing container storing water, it is possible to efficiently obtain charcoal cooled at once from the red-hot state, Can be uniformly impregnated with water, and the effective use of charcoal can be facilitated.
